Formação do professor para trabalhar com recursos de tecnologia assistiva: um estudo de caso em Mato Grosso

Due to the process of educational inclusion, it is necessary for the teacher who works with disabled students to acknowledge and master the resources of assistive technology equipment available in Brazil. The objective was to identify the presence of these resources at school and evaluate, having the teacher as the evaluator, the conditions of dealing with the Assistive Technology resources and equipment. The sample consisted of 14 teachers who work in the Resources Multifunction Classroom and 18 regular classroom teachers who have disabled students enrolled in their classrooms. Data collection was performed through the TAE Questionnaire - Assistive Technology for Education. The data collection was performance in groups during the training course sponsored by the Education Department of Rondonópolis as part of the Program of Continuing Education Training for Managers and Educators - Inclusive Education: The Right to Diversity. The questionnaire data indicated differences between the two groups mentioned. The teachers of the Resource Classes indicated that Assistive Technology resources are now being introducing at schools and that over 50% of this group understand the resources presented on the questionnaire. Most of the regular classroom teachers is still unaware of the Assistive Technology resources and equipment. Regarding the dealing of these resources the group of teachers from the multifunctional classroom is better prepared to use this technology. The data suggest the need for investment in acquisition and training of teachers in relation to Assistive Technology resources.

Estudo e analise dos sistemas de proteção em subestações automatizadas de energia elétrica

Electrical energy is present in the lives of all people and is extremely important that it be delivered to end users with plenty of quality, safety and low costs. The electric power substations are responsible for transmission and distribution of electricity generating sources to consumers, and with technological advances and the subsequent automation of same, the electricity began to be delivered with greater continuity and reliability. Protection systems in substations are largely responsible for making the electricity reaches the final consumer with quality, since their function is to prevent the spread of any type of failure occurred at any point of transmission to the load centers. These systems consist primarily by the current transformers and potential, by the protective relays and circuit breakers and switchgear. The processors send the necessary data to the relays and, if those detect any abnormality in the system, operate the opening command of the branch circuit breakers to isolate where the fault. Therefore, it is essential to better understand the operation of such equipment, as well as the overall system. This work aims to study the main substation equipment, current transformers and potential and, especially, protection relays, in order to obtain the advantages that automated systems can provide

Uso do ATP para simulações de descargas atmosféricas em para-raios de 15 kV dos serviços auxiliares de subestações de energia elétrica

This paper addresses the topics required for the selection of surge arresters used, the output of autotransformers, which protect the system Auxiliary Services (SE) of an electrical substation. Surge arresters used are part of the Protection System Lightning (SPDA). Transmission lines mostly run through regions with orographic well diversified and have constant weather changes, which lead to many undesirable interactions with electromagnetic phenomena, such as giving rise to blackout on 10 November 2009, which left nine states without power, which led to unplanned shutdowns in the system that left millions of people without electricity. This work of completion is to determine whether the method used in the selection of surge arresters meet the protection needs faced by a substation auxiliary services, through the use of software use ATPDraw

Implementação de um tuboexpansor na refinaria do Planalto Paulista – REPLAN com objetivo do aproveitamento da energia contida nos gases residuais do FCC – Fluid Catalytic Cracking na geração de energia elétrica

The steel type AISI 4130 (ultra-high strength steel) is an alloy of low carbon and its main alloying elements are chromium and molybdenum, which improves the toughness of the weld metal. It has numerous applications, especially where the need for high mechanical strength. It is widely used in equipment used by the aviation industry, such as cradle-tomotor, and this is the motivation for this study. Cots are of fundamental importance, because the engine supports and maintains balance in the fixed landing gear. This equipment is subjected to intense loading cycles, whose fractures caused by fatigue are constantly observed. Will be determined the effects caused by re-welding the structure of aeronautical equipment, and will also study the microstructure of the metal without welding. The studies will be done on materials used in aircraft, which was given to study. The results provide knowledge of microstructure to evaluate any type of fracture that maybe caused by fatigue. Fatigue is a major cause of aircraft accidents and incidents occurred, which makes the study of the microstructure of the metal, weld and re-solder the knowledge essential to the life of the material. The prevention and control of the process of fatigue in aircraft are critical, since the components are subjected to greater responsibility cyclic loading

Principais práticas e indicadores de sustentabilidade corporativa no setor de energia elétrica no Brasil

The questions involving environment and society have been increasingly considered into account when companies make business decisions. However many of them have not yet incorporated sustainability effectively in their business plan, sometimes performing only a few external actions and outside their area of expertise. The concept of corporate sustainability is within this context, and therefore the practice of companies consider, the environmental and social issues into their strategies, along with economic issues. This work has as main objective to identify what are the key indicators and related practices of the concept of corporate sustainability that has been introduced in companies on environmental reference of a certain sector of the Brazilian economy. The sector that was chosen is electric power, having enormous significance both in economy, society and environment.

Geração de energia elétrica a partir da concentração solar

The current world's need for clean and renewable energy sources aligned with the strong Brazilian growth looking to diversify its electric power generation sources, highly dependent on hydropower and petroleum encourages the implementation of technologies that reach this growth with diversity and cleaning. The sun energy source is considered inexhaustible and can meet the demand for energy through thermo solar plants to generate electricity. Several technologies are being studied and developed in the world and they can be used to generate electricity from the solar concentration, but in Brazil its use is still not found commercially. It is therefore essential to understand these technologies and develop knowledge about them so they can be implemented in Brazil. This work brings an overview of the thermo solar generation in Brazil, showing the different technologies and a thermodynamic simulation of one of such technologies considering a hybrid plant with complementary generation biomass, aiming at the generation of 1 MW in the Brazilian Northeast

Análise comparativa entre Brasil e Alemanha sobre autoprodução de energia elétrica residencial

The energy crisis has affected many countries. With the growing warning with the emission in the atmosphere and the lack of resources, the seek for sustainable sources for energy genaration have become even bigger. Some Countries, as Germany, started first in this journey, creating an incentive program to self-generation with renewable sources (wind, photovoltaics, biomass, etc.), giving priority for smaller plants. In Germany the program called EEG started in 2004. In Brazil, since the beggining of 2012, the self-generators did not know how they could be beneficted for self-generation, and self-generation didn't become commun in the country. However, with NR 482, of April 17th, 2012, the parameters were defined, and the self-generator could have a guideline. Therewith, studyies can be redirected for a better knowlegde of the conditions the self-generator will be sujected, in addition to Germany's case as reference to compare with Brazil's case. In this paper these studies are made, focused in wind power (wind turbines) and photovoltaic panels
